Marzzacco Niven & Associates approaches complex Social Security Disability Insurance claims by treating each case as a detailed evidentiary matter rather than a simple form submission. The firm gathers medical records, work history, functional limitations, and vocational evidence to show that a claimant cannot sustain substantial gainful activity.
The firm was founded in 2008 by Katherine L. Niven and Christopher J. Marzzacco. Niven previously served as Chief Counsel for the Pennsylvania Bureau of Workers’ Compensation and later worked as a workers’ compensation law judge.
Marzzacco Niven & Associates uses that experience to prepare claims that can withstand close review by Social Security judges.
What Makes an SSDI Claim Complex?
An SSDI claim becomes complex when medical evidence conflicts, a person has several impairments, or the agency questions whether the claimant can still perform past work.
Social Security applies a five-step evaluation. It considers current work, impairment severity, whether the condition meets a listed impairment, ability to perform past work, and ability to adjust to other work.
How Does the Firm Build the Record
The attorneys review the applicant’s medical file, employment history, daily activities, and prior Social Security decisions. They identify missing professional opinions, inconsistent restrictions, treatment gaps, and evidence that does not connect a diagnosis to work limitations.
The firm then translates clinical findings into practical restrictions. Severe arthritis may matter because it prevents prolonged standing, lifting, or reaching.
Is Medical Evidence Important
SSDI is not granted merely because a person has a serious diagnosis. The Social Security Administration generally needs objective findings, treatment notes, imaging or testing when available, medication records, hospital records, and provider opinions explaining functional capacity.
A primary-care doctor, orthopedic surgeon, neurologist, pain professional, psychologist, or psychiatrist may describe different limitations.
How Are Appeals and Hearings Managed?
The firm represents clients from the initial application through administrative appeals, federal district court, and the Third Circuit Court of Appeals. This continuity matters because a missed deadline or incomplete record can limit the evidence available later.
Before a hearing, the attorney prepares the client to accurately describe symptoms, treatment, and limitations.
What Experience Supports Its Disability Work?
Katherine Niven’s background as a former workers’ compensation judge and bureau chief counsel gives the firm insight into how disability decisions are reviewed. Christopher Marzzacco has three decades of litigation experience and has secured multiple seven-figure settlements in catastrophic injury and wrongful-death cases.
The firm’s attorneys have received recognition from The Best Lawyers in America, Super Lawyers, Rising Stars, The National Trial Lawyers “Top 40 Under 40,” and Multi-Million Dollar Advocates. U.S. News & World Report has also recognized the firm among “Best Law Firms.”
Where Does the Firm Practice?
Marzzacco Niven & Associates serves clients across Pennsylvania from its Harrisburg headquarters and offices in York, Carlisle, Lebanon, Lancaster, Carbondale, Wyomissing, and Chambersburg. The firm handles Social Security Disability, workers’ compensation, personal injury, wrongful death, and employment-discrimination matters.
What Should Claimants Do Next?
- Gather medical records, test results, medication lists, and provider contact information.

- File the SSDI application promptly and retain every SSA notice.
